问题描述

我想创建一个接受双均值、双偏差并返回一个正态分布的随机数的函数.

I would like to create a function that accepts Double mean, Double deviation and returns a random number with a normal distribution.

例如:如果我传入 5.00 作为平均值和 2.00 作为偏差，68% 的时间我会得到一个介于 3.00 和 7.00 之间的数字

Example: if I pass in 5.00 as the mean and 2.00 as the deviation, 68% of the time I will get a number between 3.00 and 7.00

我的统计数据有点弱......任何人都知道我应该如何处理这个问题?我的实现将是 C# 2.0，但只要数学函数是标准的，就可以用您选择的语言回答.

My statistics is a little weak…. Anyone have an idea how I should approach this? My implementation will be C# 2.0 but feel free to answer in your language of choice as long as the math functions are standard.

我认为这个实际上可能成为我正在寻找的东西.任何帮助将其转换为代码?

I think this might actually be what I am looking for. Any help converting this to code?

预先感谢您的帮助.

推荐答案

参见这篇 CodeProject 文章:简单的随机数生成.代码很短，可以从均匀分布、正态分布和指数分布中生成样本.

See this CodeProject article: Simple Random Number Generation. The code is very short, and it generates samples from uniform, normal, and exponential distributions.
